Embodiment Construction

[0044] Below in conjunction with accompanying drawing (Fig. 1) the present invention is further described.

[0045] The traditional prosthesis manufacturing method has many human factors, requires doctors to have rich experience, and needs to be revised and confirmed repeatedly during the production process, and the precision of the prosthesis is poor and the surface is rough. The present invention provides a method of making a prosthesis using computer aided manufacturing technology (CAD / CAM) and rapid prototyping technology. This method uses CT and other medical image technology, three-dimensional image processing technology and rapid prototyping technology to obtain the patient's craniofacial data very accurately. The prosthesis that is closer to the original appearance of the patient greatly compensates for the poor precision and rough surface of the traditional prosthesis. Moreover, the workload of doctors is obviously reduced, and unnecessary troubles brought to patient...

Abstract

The invention provides a method for producing a prosthesis, which adopts the computer-aided manufacturing (CAD / CAM) technology and the rapid prototyping technology for producing the prosthesis. The usage of the method can very accurately obtain the craniofacial facial data of patients; according to the data, the prosthesis, which can perfectly attach the defected part of patients and is more close to the original appearance of patients, can be designed.

Description

technical field [0001] The present invention relates to the repair technology of craniomaxillofacial defect, and the repair refers to choosing to use a prosthetic body to repair. In particular, the invention relates to a method of making a prosthesis. Background technique [0002] Craniomaxillofacial defects caused by tumor resection or trauma are very common. Sometimes it is difficult to obtain ideal results or even impossible to reconstruct such defects by using autologous tissue repair by surgical methods. At this time, you can choose to use prosthetics body to repair. [0003] Craniomaxillofacial congenital defects, trauma, and postoperative deformities of malignant tumors exist in the face that represents personal characteristics, completely destroying its aesthetic appearance and function. No matter the size of the defect, the function. Aesthetic defects will bring serious mental burden to patients, and their pain and despair are unimaginable for healthy people. ...
